IMPROVED STRAW-GUTTER.

1'0 ALL WHOM'IT MAY CONCERN:

Be it known that I, ADDISON BUCH, of West Earl township, in the county of Lancaster, in the State of Pen nsylvania, have invented a new and useful Improvement on a Straw or Fodder-Cutter; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, referencebeing had to the accompanying drawings making a part of this specification, in which Figure 1 is a perspective view of a. straw or fodder-cutter, with my improvement in place.

Figure 2 is the improvement detached, together with the ordinary bed-plate or rim.

The nature of my invention consists in providing the mouth of'my box with an edged metallic plate, on a spring-block 0r boarch'coming even with the bottom plate of the box,'so that the knife enters between the mouth and spring-plate to insure a smooth and certain cut, without any crowding or choking of the straw or hay. While cutting I also increase the leverage by the manner I form and fasten my knife.

To enable-others skilled in the art to make and use my invention, it is only necessary to say that the iron plate C in the bottom of the box, like the ordinary frame, is laid across the mouth, the front edge flush, against which the blade of the knife slides while cutting. The blade or knife in its levered handle H slides up and down inthe slotted posts P P, with its fulcrum or pivot in P", at F. These posts are secured at top by a bevel brace-piece E, between the slots, by means of bolts and screw-nuts. By this arrangement I gain greaterleverage, and a steady motion to the lever to which the knife is attached, so as to work truly in a vertical position. The main feature of my invention, however, consists in the spring-plate A, which has a bevel upper edge, and. lies against the horizontal edge of the mouth-plate O, with a pressure given to it by the board B, to the upper inside of which the plate A is aflixed by scarfing out the board and attaching the plate flush with the wood. This spring-hoard B is secured to the cross or foot-piece of the machine, as shown, slightly inclined inwards, and with the plate A jointly actingasa spring in holding the upper edge of the plate against the knife, which passes between said plate A and edges of plate 0 in the mouth of the box, thereby yielding aclean and smooth cut, and so as to prevent any choking whatever, while the long slots and leverage make it as easy to work, as it cuts smoothly. These combined features make ample amends for the spread of the front portion, and makeit a highly desirable invention, and will be duly appreciated by those who may use it.

I am aware that various improvements are patented on straw and fodder-cutters, but I am not aware that a metallic or steel plate was ever applied and combined substantially as herein shown.

What I ciaim as my invention, and desire to secure by Letters Patent, is-

The construction and arrangement of the metallic plate A and springboard B, in combination with the bottom plate C, and arrangement of the knife D and lever H, in the'manner and for the purpose specified.
